Ask HN: Does HN automatically censor some new posts?

I just tried to submit a post for a kickstarter project, but when I log out the article disappears from the "New" page.

This is the item ID. https://news.ycombinator.com/item?id=7902079 which I can see fine when I'm logged in, but it's blank when I log out.

Is there some unwritten policy disallowing links to kickstarter? People seem to be able to read my comments and reply to them fine, and I don't post often, so I'm not sure what is going on.
